Sodium glucose transporter inhibition in heart failure From an unexpected side effect to a novel treatment possibility.

Diabetes Res Clin Pract 2021 Apr 9:108796. Epub 2021 Apr 9.

Department of Medicine K2, Karolinska Institutet 171 76 Stockholm, Sweden. Electronic address:

Sodium-glucose transporter-2 inhibitors (SGLT2i), originally launched as glucose-lowering drugs, have been studied in large cardiovascular outcome trials to ascertain safety. Surprisingly, these compounds reduced the risk of cardiovascular events (cardiovascular death, non-fatal myocardial and non-fatal stroke) and total mortality. The mechanisms behind this benefit are only partly understood, but a major contributor is the reduction of heart failure hospitalisations, evident already within weeks after the initiation of the SGLT2i.

Energetic constraints imposed on trophic interaction strengths enhance resilience in empirical and model food webs.

J Anim Ecol 2021 Apr 12. Epub 2021 Apr 12.

Institute of Biochemistry and Biology, University of Potsdam, 14469, Potsdam, Germany.

Food web stability and resilience are at the heart of understanding the structure and functioning of ecosystems. Previous studies show that models of empirical food webs are substantially more stable than random ones, due to a few strong interactions embedded in a majority of weak interactions. Analyses of trophic interaction loops show that in empirical food webs the patterns in the interaction strengths prevent the occurrence of destabilizing heavy loops and thereby enhances resilience.

Can We Decrease Epicardial and Pericardial Fat in Patients With Diabetes?

J Cardiovasc Pharmacol Ther 2021 Apr 12:10742484211006997. Epub 2021 Apr 12.

Department of Clinical Biochemistry, Royal Free Hospital Campus, University College London Medical School, 9687University College London (UCL), Pond Street, London, UK.

Diabetes mellitus (DM) is a chronic and complex metabolic disorder and also an important cause of cardiovascular (CV) disease (CVD). Patients with type 2 DM (T2DM) and obesity show a greater propensity for visceral fat deposition (and excessive fat deposits elsewhere) and the link between adiposity and CVD risk is greater for visceral than for subcutaneous (SC) adipose tissue (AT). There is growing evidence that epicardial AT (EAT) and pericardial AT (PAT) play a role in the development of DM-related atherosclerosis, atrial fibrillation (AF), myocardial dysfunction, and heart failure (HF).
